We have just given two names to the same key. We say that C sharp and D flat are
enharmonic because they sound the same but have different names.

just those of the black keys, have at least two enharmonic designations. This is
because "sharp" and "flat" can apply to any pitch. Thus, C is enharmonic to B sharp,
because "sharp" simply means a pitch is raised a half step. Similarly, E is enharmonic
to F flat. Remember that a sharp or flat is not necessarily a black key.
